Answer:

What is surface tension?

Explanation:

Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.

Surface tension forces between mucosal surfaces play an important role in the pathogenesis of the disease. The obstruction of upper airway elicit the activation of autonomic nervous system, hypoxemia, and arousal from sleep.

A particular beer is 65.0% ethanol by volume . If a single bottle of beer contains a total of 750.0 mL of beer, what volume, in mL of ethanol (C₂H₆O), are present in the bottle?
SHOW CONVERSION

Answers

The volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L

HOW TO CALCULATE VOLUME OF ETHANOL:

According to this question, a particular beer is 65.0% ethanol by volume. This means that the beer contains 65/100 of ethanol.

If a single bottle of beer contains a total of 750.0 mL of beer, the volume of ethanol in the bottle is calculated as follows:

= 65/100 × 750

= 65 × 7.5

= 487.5mL

Therefore, volume in mL of ethanol (C₂H₆O) present in the bottle is 487.5L

When two atoms bond chemically it is because of the interaction between
A) the nuclei of each atom.
B) the protons in each atoms.
C) all electrons in the atoms.
D) the valence electrons in each atom.

Answers

Answer:

C

Explanation:

It depends on the bonding for an explanation.

If one atom is a metal and one is a non metal it will be ionic. This is because one atom transfers its electron to the other atom giving them both a charge. They will then be bonded due to opposite forces of attraction.

If both atoms are non metals it will be covalent. Electrons pair together in the center of two atoms that have merged together and they share their electrons.

Which atom would you expect to have a larger atomic
radius—francium or tennessine?

Answers

Answer:

Francium bc it has the largest atomic radius

Francium has the greatest atomic radius. Despite being a highly radioactive metal with a short half-life, francium has little environmental impact.

What is francium?Francium is a chemical element with the atomic number 87 and the symbol Fr. Francium-223, its most stable isotope, has a half-life of only 22 minutes, making it extremely radioactive. It is the second-most electropositive element and the second-rarest naturally occurring element, trailing only caesium.Francium has been used to study atomic structure in addition to being used in chemistry and research. It is used in the diagnosis and treatment of cancer. It is also used in a number of spectroscopic experiments. Despite being a highly radioactive metal with a short half-life, francium has little environmental impact. Francium is created by bombarding radium with neutrons in a nuclear reactor. It is also possible to create it by bombarding thorium with protons.

Suppose you did the lab and someone came and said your unknown acid sample was
actually HCl instead of H2SO4. Everything else remains the same; the standard acid was H2SO4,
the base was NaOH. What would change in your final calculation of the unknown acid
concentration

Answers

Answer:

H2SO4

Explanation:

because it's not more acidic

         Both sulfuric acid and hydrochloric acid are potent acids, but hydrochloric acid is stronger. Because HCl is monoprotic and H2SO4 is diprotic, they differ mostly in their acid types.

Can HCl be substituted for H2SO4?

     Instead of using hydrochloric acid, sulphuric acid (H 2 SO 4) is preferred because: This acid is commonly utilized for a variety of neutralization reactions. Sulphuric acid is more potent than all other acids and is also simpler and safer to use. Even if there is a risk for negative reactions, they are uncommon.

      The majority of the time because it is for a redox reaction or titration in which HCl would react to produce chlorine on its own. You could use phosphoric or sulfuric acid.

       In this situation, H 2 SO 4 is preferable to HCl. Due to the considerable acidity of H 2 SO 4, the solution is made to be more acidic than HCl. As a result, the findings of titration using H 2 SO 4 are more precise. H 2 SO4 generates two hydronium ions, whereas HCl only generates one.

         It shows how many protons split apart to create hydronium ions. The acid will be more potent the lower the pKa value. Therefore, we can conclude that HCl is more acidic than H2S O 4.

On Earth, lava tubes form during sustained volcanic eruptions, when lava flowing through previously solidified masses leaves behind empty channels in the rock

Explanation:

The lava, itself (when liquid) is very much above the boiling point of water, so it is not wet with liquid water, so it's a no in that sense,' he writes. ...

Some chemicals, most often inorganic salts, in the laboratory have the nasty tendency to absorb water from the atmosphere. This property is called hygroscopicity. Anhydrous (water-free) Cupric Perchlorate [Cu (ClO4)2] weighs 262.447g/mol, but after sitting on out on the bench top absorbs water from the air and now weighs 370.540g/mol. How many water molecules did our Cupric Perchlorate absorb?

Answers

If an anhydrous Cupric Perchlorate weighs 262.447g/mol initially and weighs 370.540 g/mol after sitting on the bench to absorb water from the air, the number of water molecules absorbed would be 6 moles.

First, let us calculate the amount of water gained during the course of staying on the bench:

Water gained = weight after gaining water - initial weight

                       =  370.540 - 262.447

                        = 108.093g/mole

The total amount of water gained per mol is 108.093. Each water molecule weighs 18.015 g/mole. Thus, the total number of water molecules that will sum up to 108.093 would be:

                         108.093/18.015 = 6 moles

In other words, the number of water molecules absorbed by the Cupric Perchlorate is 6 moles.

Formula: acceleration = (v - u) /t where v = final velocity, u = initial velocity and t = time

a = 2.5 m/s²

u = 5.0

v = 27. 0

t =?

at = v - u

t = (v - u) /a
